The stereoselective synthesis of a bicyclic ring system related to Neocarzinostatin and Kedarcidin Chromophores is described; key steps involve stereoselective conjugate addition of an enediyne to an enone and intramolecular aldol reaction of a cobalt complexed alkynyl aldehyde.
base mediated isomerisation reaction. These species and their derivatives can be used to provide a wide range of synthetically useful intermediates by participation in a variety of stereoselective transformations. These include: nucleophilic and conjugate addition, intermolecular cycloaddition, intramolecular free-radicalcyclisation and palladium mediated coupling reactions.
